I claimzl. An electromotor comprising a centrally arranged stationary field magnet, a shaft journaled therein, 'a plurality of Wings sev cured to said shaft, commutator segments integral with thewings, and armature coils carried by the Wings.

2. An electromotor comprising a centrally arranged stationary field magnet, a shaft journaled therein, a plurality of insulated Wings secured to said shaft, and armature coils carried by the Wings.

3. ln an electromotor, a support, a plurality of. insulated Wiiigs secured thereto, armature coils carried by said Wings, and means for conduetively connecting any one coil with one of 'the adjacent Wings.

4. In an electromotor, a support, a plurality of insulated Wings secured thereto, armature coils carried by said Wings, one terminal of each coil being conductively connected to its Wing While its other terminal is connected to one of the adjacent Wings. v

5. ln an electromotor, a support, a plurality of insulated Wings secured thereto, armature coils carried by said Wings, and a contact spring eonductively connected to each coil 1and enga-ging one of the adjacent Wings.

6. In'an electromotor, a shaft, a support 'the brackets of each Wing, and a coil surrounding each core.

8. In an electromotor, a shaft, a support fast thereon, a plurality of conductive Wings' secured to and insulated from the support, brackets fastened to the Wings, a core connecting` the brackets of each Wing, a coil surrounding each core, and a spring conductively connected to cach coil and engaging one of the adjacent brackets.

9. ln an electrolnotor, a cent-rally arranged field magnet comprising a tubular core, pair of opposed L-shaped pole shoes secured thereto, and an annular field coil encircling the core and accommodated between the pole shoes, combined with a shaft journaled in the core, a .plurality of insulated conductive wings secured to theshaft, commutator segments integral with the wings, armature coils carried by the wings, and contact springs that connect any one coil With vone of the acent Wings.
